My new van hasn't got any retaining straps on the drop down locker doors on the outside of the van lwhich the other van did have.I like to have these because the locker door can be held at about 90 degrees and make a table like shelf which is great for standing light objects on.Trouble is I can't remember how the straps were fitted on my previous van,even though I had it for 5 years!Could any kind person post a picture of how these are fitted please,so I can see what bits I need and what and where to fit.Many thanks in advance.
